The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will investigate the… (More)

We measured temperature dependence of alpha/gamma-ratio of three sample pieces of Ce 0.5 mol% doped Gd2SiO5 crystalline scintillator, which are cut from different ingots and have a dimension of… (More)

We developed transparent ceramic scintillators of Ce doped YAG, Ce and Nd codoped YAG, and Ce doped (GdY)AG, respectively. We cut them with a size of 5 times 5 times 5 mm3 for Ce:YAG and (Ce,Nd):YAG,… (More)

The hard X-ray detector (HXD-II) is one of the three scientific instruments onboard Japanese X-ray astronomy satellite Astro-E2 scheduled to be launched in 2005. This mission is very unique in a… (More)

Suzaku is the fifth Japanese astrophysical satellite, devoted to study high energy phenomena in the X-ray band of 0.5-600 keV. It was successfully launched from Uchinoura Space Center in Japan on… (More)

We summarize significant improvements which have been achieved in the development of Astro-E2 Hard X-ray Detector (HXD-II). An expanded energy range and better energy resolution have been achieved… (More)
